Please help, I'm running a Dell XPS with Vista home premium and a 500GB HDD. I have around 10GB of video and 5GB music stored plus a few prorams but nothing big.However my HDD is reading as 107GB of used space.I have Mcafee security and scans show no spyware malware or viruses.Surely Vista can't be using this much memory,if not can anyone suggest where it may be being used? thanks
HDD space and memory are two completely different things.
You may only have 10GB of videos and 5GB of music on your PC but you also have an operating system, probably many other programs (MS Office, Adobe, Internet Explore, an e-mail client etc, etc) and the various files (Word, Excel) associated with those programs.
I assume you also have AV and anti-malware software loaded.
All of these things take up yet more space on your HDD. It's surprising how quickly it all adds up.
And if you don't have a regular PC housekeeping regime, you'll have God knows how many temporary files and System Restore points - again, they all take up HDD space.
UIf your machine is running without any problems, ie you are not likely to need to restore to a previous date, then turn off System Restore, reboot the computer, turn System Restore back on and check space free on your hard drive. It should free up a lot of space.
